Then (As mentioned) your setup is wrong. Your ISP cannot block your internal traffic.

Internet -- external --> Routier -- internal --> computer1 / 2 ...

See?

So why don't you just say who your ISP is? I doubt that you're the only one using them, and if others here who are on the same ISP aren't having any issues (and I seriously suspect that will be the case) then it's not your ISP -- as, it seems, many have tried to tell you since the start. So who's the ISP?

Third year student in telecommunications, and yet they haven't taught you to pick up the phone and speak to an ISP to ask a simple question? I despair!

Well I am totally not shocked by this.

Its what I have come to expect from people on the net... thinking they know everything. People on here are trying to help and everytime someone makes a suggestion you dismiss it.

There is no way that your isp is going to inspect every packet of data to see how many machines are using your connection.

Therefore this is either:

a ) hardware issue

b ) user error

I suspect the latter.

Who is your ISP for starters?

Yeah, man I wish it worked even if I use a router.

comp2 had this ip:

What IP? What is it about giving even the hint of info -- so we can help you? You have yet to give us the MODEL NUMBER of your modem device.. for all we know its a gateway doing nat? and not a modem at all. Your stepping on it lan IP with the IP of the of ICS interface, etc..

Lets assume some stuff, your modem is not a gateway.. So you were/are using ICS.. the ip of comp1 nic1 would be some public ip

comp1-nic1

ip: public

netmask: whatever

gateway: public

dns: ISP dns

This computer works.

comp1-nic2 (ICS interface)

ip: 192.168.0.1

netmask: 255.255.255.0

comp2

ip: 192.168.0.2

netmask: 255.255.255.0

gateway 192.168.0.1

dns: 192.168.0.1

From comp2 you can ping the ICS interface?

Can you ping the PUBLIC IP address of your machine?

Can you ping the Gateway IP of your Public Interface from computer2

Can you ping some outside IP address? Resolve the IP from comp1 and then try to ping it on comp2, etc

As already mentioned - it just may be a dns issue? Without some info to work with - no one can help you.

I would forget ICS, you have a router.. take a few minutes and set it up! Shutoff your modem, connect your router.. Boot up the modem, then turn on yoru router. Connect to its Lan interface.. does it get a WAN IP from your isp? If not - clone the machine that works MAC.. shutdown the modem and router, and try again.

I Thank you BudMan and I thank everybody else for their inputs.

I just got back from gym...Im gonna give it a try a bit later and I'll let you know if it worked or not. http://www.ipko.net is my ISP, my modem is webstar DPC 2100, I dont own a public IP, what else to tell...anyway I'll try again a bit later and see what happens.

Umm, maybe you don't actually own a public IP, but the public IP is your external IP, your Internet IP. You do have one otherwise you'd never get online ...

have you thought it might be something with your mac address that your router wasn't working? Most isps tie the public ip to one mac address, so try giving your router the ip of nic 1.

Didn't work!

Here is the pic of comp1's configuration:

@BudMan

Can you ping the PUBLIC IP address of your machine? Yes, from the comp2 I can ping the"server IP" in this issue, and I can ping the 192.168.0.1 fine.

The comp2's configuration is:

IP:192.168.0.2

Sub.mask:255.255.255.0

Gateway:192.168.0.1

Prefered DNS server:192.168.0.1

Alternate DNS server: I left it blank

And the interesting thing is that when I open from comp2 IE say google.com it finds the site saying "the webside found. Waiting for reply..." but after a while it just shows the page can not be displayed!

EDIT: I also tried pinging 66.6.66.6 from the comp2 but it gave me request timed out!

Not the Computer, check the Wan interface within the web interface of your router! it should have a public IP. Your computers get a private address so they are picking up the correct address. READ budmans posts! he explains everything greatly!

So in summary of what he said IF you are using a ROUTER NOT ICS. If ICS, reference back to budmans post.

You connect your modem to the WAN interface on router. Then connect comp1 to the LAN. Turn off the router and modem. Turn on the modem. Then turn on the Router. Access the router by http://192.168.0.1

Then check the WAN interface if he has an ip. If not, clone the Mac address from comp1. You can get the mac address of comp1 by typing ipconfig /all. write down the 16 hexidecimal number and then access your router from above address and find where to clone the mac address. Then turn off modem and router, turn on modem, then router. Check WAN IP again. You will NOT get internet if you are not getting the IP from your ISP.

Your computers will get addresses from a dhcp pool of 192.168.0.0 - 192.168.0.254 as you can see from your comp1. comp2 will probaly get 192.168.0.3.

192.168.0.1 is your router. if you can ping that, you know you can connect to the router.

First off let me say I think your correct in addressing what the problem is.however you are incorrect about 1 thing. an isp can and does inspect all data coming from a certain account. example ive done security work for time warner cable they are able to tell how many modems are connected in your house whether time warner owns them or not if your running routers. how many, how many computers in your house are connected to the net, they know if your running servers and how many people are connected to your connection or server. they usually dont see what files are being uploaded or downloaded but they can if they wish to with little more investigation. they can see how much bandwidth your using up and down and without much effort they will know if your file sharing etc. they can aslo tell you what i.ps or websites that are visited in a certain time frame and how long you were there etc.and it doesn't matter what firewalls hardware or software your using they know if they choose too.

they usually dont do these things unless there is reports of something or unusual activity on your account. but they can.just like we can look at your account and tell you what channel your watching at that exact moment if you watched pay per view etc if you ff or rewound paused etc. this isnt public knowlede and they instruct employees not to tell the customer unless they ask point blank. but these things can and are done.

So, let's just say it clear.

You have COMP1 connected to the internet. Your modem is connected to COMP1 via NIC1.

Then, at the same time, COMP1 is connected to COMP2 via NIC2.

COMP1-COMP2 are on a LAN, and COMP1-MODEM are on an LAN too.

Am I right?

yeah you are right.

So, you have an internal IP for nic1 and another internal IP for nic2. I suppose the modem also has an internet IP, which is the gateway.

If that is the case, then:

1) bridging both nics so that comp2 can directly interact with the modem may not be a solution, unless the modem is already prepared to handle several computers. I guess nowadays all modems have NAT and stuff, but you can never be sure.

2) Using xp's built-in feature of sharing your internet connection. I have no experience with this, but I suppose this would turn COMP1 into a gateway COMP2 could use to access the internet?

i dont have shown gateway IP, but i can ping my WAN IP.

By WAN IP you mean the external IP that I could ping too from my computer?

If COMP2 can ping external IPs then it can be a DNS problem. Have u tried accesing any webpage by the IP?

Didn't work!

What didn't?? You gave us no details of what you tried - did you try hooking up the router? Your on a PPPoE connection - then you will have to setup your router with your login info for it to work.

How exactly is your modem connected? USB? Your nic1 shows limited or not connectivity..

Internet didnt work in comp2. I didnt try hooking up the router. I tried only the method of sharing internet connection through NIC2 to comp2.

My modem is connected to NIC1 eventhough it shows limited or no connectivity the internet works fine!
